Basically what the title says. I was out of the house today and got a notification that I'm at 100% utilization which it does show on the main screen however if I go into main it shows 6.5 TB free. If I go into the share it shows a large amount unallocated. I am using btrfs filesystem because I have pretty much every piece of data hardlinked somewhere as well as various drive sizes. I am planning to add another drive this weekend as a bandaid but I would love to know what's actually happening here.

Pool went readily because it ran out of space during the balance, note that RAID1 metadata requires for it to be stored in at least two devices, and 2 out of the 3 pool devices are completely allocated. You would need to free up some space before resuming the balance or not use RAID1 for the metadata.
